Problem:  Use the figure and information provided below to answer the following question. LO 10d: For this figure, the moment of inertia about the x-axis is and the moment of inertia about the y-axis is .  What is the polar moment of inertia about the origin?  Show your work on a separate piece of paper to be uploaded after you complete the quiz.

True/False:  Indicate whether the statement below is true or false.  If the statement is true, justify your reasoning.  If the statement is false, correct the statement to make it true or justify why it is false. LO 10c: The parallel-axis theorem transfers the moment of inertia from an axis that goes through the centroid to some other axis.

Problem: Use the figure below to answer the following questions for finding the moment of inertia about the y-axis.  Hint:  To find the moment of inertia, break the figure into: 1) a rectangle that is 6 in by 10 in, 2) a triangular cut that is 3 in by 6 in, and 3) a circular hole that has a radius of 2 in. LO 10c: Determine the moment of inertia about the y-axis. Show your work on a separate piece of paper to be uploaded after you complete the quiz. Solution Units

Problem: Use the figure below to answer the following questions for finding the moment of inertia about the x-axis.  Hint:  The recommended different element you should use is pictured for you. LO 10b: Why is it better to use the horizontal differential element shown (vs. a vertical one) to find the moment of inertia about the x-axis? Justify your response.
